Moving on from the hunting theme but staying with shooting, here's another interesting piece.
I've never been able to get to the bottom of what this organisation was actually called. The badges & pins simply have "KKS" on them, Hüsken lists the name as "Deutsche Kartell für Jagd- und Sportschießen". However an earlier booklet Deutschland im Spiegel seiner Abzeichen 1930-45 by Brüggemann & Rowedder list the organisation as "Kleinkaliber-Sport e.V." which fits in the KKS far better than Hüsken's suggestion.
